Business Components Client Methods

Question

I have a question regarding BC4J and client-callable custom methods.
There are certain custom methods (ie to retrieve xml for that object and parse it with a stylesheet), that I've written for my BC4J Viewobjects that all ViewObjects in my project will be requiring.
So far, I've had to copy and paste the code required for these methods into each view object I create. This seems very inefficient, yet inheritance is out since all view objects already inherit from the oracle.jbo.server.ViewObjectImpl class.
Is there anyone who has found a more elegant solution for doing this?

Danny,
There's no requirement that your view object inherit exactly the oracle.jbo.server.ViewObjectImpl class. The only requirement is that they ultimately derive from that class. That means that you are free to subclass ViewObjectImpl with your own com.clinicare.framework.ViewObjectImpl and then use this enhanced version of ViewObjectImpl as the base class for all the View Objects you create in BC4J.
You could of course manually change the base class for each one as you create them, but a better way is to "teach" the BC4J design time wizards about your preferred framework base class specializations and then the wizards will default your classes instead of the default class names.
See the Framework Base Classes tab of the Wizards | Business Components Properties wizard to set these.
